   Can somebody explain why a square root is also considered a flop? Surely that involves more work than the other four operations the article listed. Is there some hardware algorithm for the square root that is as fast as (e.g.) division?

   I thought the Latin phrase was "post hoc ergo propter hoc". Is "cum hoc..." also used?

   I think people are misunderstanding this; it's pedagogical. From the link: 'I want to use it as an exercise for you in finding hacks, attacks, defects, and bugs by going through "K&R C" to break all the code...When you are done doing th

   I think you're missing the post's author's point. He isn't saying "after wars the DJIA goes up", he's saying "after periods of inflation, the DJIA goes up" (see the title of the graph). Note he still doesn't mention 1929-1933, which seems

   The Wired article says the "X-37 periodically changes orbits". However, the linked article from the CS Monitor ( http://www.csmonitor.com/Science/2010/0824/Secret-Air-Force-... ) only indicated one orbit change.
